240KW duct-type electric heater

I. Overview of 240KW duct-type electric heater:

Air duct electric heaters are mainly used for air heating in ducts, available in three specifications: low temperature, medium temperature, and high temperature. Their common structural feature is the use of steel plates to support the electric heating tubes to reduce vibration, and all junction boxes are equipped with over-temperature control devices. Additionally, for ease of control, apart from over-temperature protection, a parallel operation device must be added between the fan and the heater to ensure that the electric heater starts after the fan. A differential pressure device should be added before and after the heater to prevent fan failure. The gas pressure heated by the channel heater should generally not exceed 0.3 Kg/cm2. If the pressure specification exceeds this, please choose a circulating electric heater. The low-temperature model has a gas heating temperature not exceeding 160℃; the medium-temperature model not exceeding 260℃; and the high-temperature model not exceeding 500℃.

Section II: Application Fields of 240KW Duct-Type Electric Heater:

Duct-type electric heaters are primarily used to heat the required airflow from an initial temperature to the desired air temperature, up to a maximum of 850°C. They are widely applied in aerospace, armaments industry, chemical industry, and many scientific research and production laboratories in colleges and universities. Particularly suitable for automatic temperature control and high-flow high-temperature combined systems and component testing. The air electric heater has a broad range of applications: it can heat any gas, producing dry, moisture-free, non-conductive, non-flammable, non-explosive, non-corrosive, non-polluting, safe and reliable heat, with quick temperature rise in the heated space (可控).

Section 3: Technical Features of the 240KW Duct-Type Electric Heater:

1. Can heat air to a very high temperature, up to 450°C, with the housing temperature around 50°C.

2. High efficiency: Up to 0.9 or above.

3. Rapid heating and cooling rates up to 10℃/s, quick and stable adjustments. No overshooting or lagging of the controlled air temperature, ensuring temperature control remains stable and is ideal for automatic control.

4. Excellent mechanical properties: Due to its special alloy material as the heating element, it outperforms any heating element in terms of mechanical properties and strength under the impact of high-pressure air flow. This is particularly advantageous for systems and accessories that require continuous and uninterrupted air heating over extended periods.

5. Durable and long-lasting, with a service life of several decades when used in accordance with the operating procedures.

6. Clean air, compact design.

7. Custom-designed air electric heaters of various types are available to meet customer needs.
